b$.$ Read the following case and draw a state machine diagram:

ABC is an online company that allows customers to buy tickets for various sporting and entertainment activities. The object $$Ticket$$ takes on many states during its lifecycle. Once the customer visits the website, the system first creates a new instance of a ticket and the ticket is considered initiated. After the customer selects an event and a seat, if the selection is valid then the state changes to reserved. The customer has $24$ hours to pay for the reserved ticket. If $24$ hours pass or the payment method isn$$t valid, then the ticket is considered canceled. If payment is valid and within $24$ hours then the reservation is confirmed. A canceled ticket can be confirmed if valid payment is provided and the desired seat hasn$$t been taken yet.
